Never challenge Kristen Stewart's strength, unless you want her to look at you with an unchanging expression for a few sustained moments. Scary stuff.
Check out a new clip from Breaking Dawn Part 2, featuring an arm wrestling contest between the gigantic Emmett and the tiny Bella:
Stewart stars along with Robert Pattinson and Taylor Lautner in the final installment of the Twilight Saga. This time, Bella and Edward's new daughter Renesmee is misidentified as an immortal child, so the Cullens band together with other vampire clans to protect her.
Ashley Greene, Maggie Grace, Nikki Reed, Dakota Fanning, Peter Facinelli (Can't Hardly Wait), and Michael Sheen also star. Take a look at these The Twilight Saga: Breaking Dawn - Part 2 character posters before the film hits theaters November 16.
